@Chuck Sartor posted:It almost looks like a 'kit bash' project. A chassis from a Lionel SD18 and a body shell from a GP38. Not 100% accurate, but fairly close.
That would bear somewhat of a resemblance, and if you're using the lionel parts you suggested than it would likely look the part in a lionel toy train fleet.
That being said: there are enough differences between the sdl39 and any other locomotive that I think it would be extremely hard (not impossible) to capture the true look with anything but a properly done brass model.
